如何在刷新时重新填充表单中的复选框并将表单值发布到页面？

I am using an ajax script to repopulate checkboxes on a page when the page refreshes or is sent to another page and then back again. The script works fine as the checkboxes will still be checked after page refresh.

The problem I have is these checkboxes work as filters. So when clicked it POSTS to the page and my php script puts each value into a string for my query. When a page is refreshed the checkboxes stay checked but are not posting the values to the page. How can I make this Ajax script POST the values of the form after it repopulates my checked checkboxes on page refresh?

Here is Ajax script:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script src="http://cdn.jsdelivr.net/jquery.cookie/1.4.0/jquery.cookie.min.js"></script>

<script>
  function handleButtonClick(button){
    if ($(button).text().match("Check all")){
      $(":checkbox").prop("checked", true)
    } else {
      $(":checkbox").prop("checked", false)
    };
    updateButtonStatus();
  }

  function updateButtonStatus(){
    var allChecked = $(":checkbox").length === $(":checkbox:checked").length;
    $("button").text(allChecked? "Uncheck all" : "Check all");
  }

  function updateCookie(){
    var elementValues = {};
    $(":checkbox").each(function(){
      elementValues[this.id] = this.checked;
    });

    elementValues["buttonText"] = $("button").text();
    $.cookie('elementValues', elementValues, { expires: 7, path: '/' })
  }

  function repopulateFormELements(){
    var elementValues = $.cookie('elementValues');
    if(elementValues){
      Object.keys(elementValues).forEach(function(element) {
        var checked = elementValues[element];
        $("#" + element).prop('checked', checked);
      });

      $("button").text(elementValues["buttonText"])
    }
  }

  $(":checkbox").on("change", function(){
    updateButtonStatus();
    updateCookie();
  });

  $("button").on("click", function() {
    handleButtonClick(this);
    updateCookie();
  });

  $.cookie.json = true;
  repopulateFormELements();


</script>

And the PHP on same page that puts what is checked into a string for my query

if (isset($_POST["2kandunder"])) {
$arguments[] = "AND `2kandunder` = 'yes'";
}
if (isset($_POST["2kto4k"])) {
$arguments[] = "AND `2kto4k` = 'yes'";
}
if (isset($_POST["4kandup"])) {
$arguments[] = "AND 4kandup = 'yes'";
}

if(!empty($arguments)) {
$str = implode($arguments);
}

And html form

 <form id="form" method="post" action="">
<input type="checkbox" name="2kandunder" class="checkbox" id="1" onchange="$('#form').submit();" <?=(isset($_POST['2kandunder'])?' checked':'')?>/> $2000 And Under   

<input type="checkbox" name="2kto4k" class="checkbox" id="2" onchange="$('#form').submit();" <?=(isset($_POST['2kto4k'])?' checked':'')?>/> $2001 To $4000

<input type="checkbox" name="4kandup"  class="checkbox" id="3" onchange="$('#form').submit();" <?=(isset($_POST['4kandup'])?' checked':'')?>/> $4001 And Up   

I have tried adding the following to my ajax but I am totally new to ajax and it was a total guess. This code makes the page start blinking and the page will go to "page not found" after about 5 seconds.

$('#form').submit(); 

As you store the cookie, you can use it information in PHP as well to repopulate the query filter and the checkboxes on the form

<?php

    $checkboxes = array('checkbox1' => false, 'checkbox2' => false, 'checkbox3' => false, 'checkbox4' => false, );

    if (isset($_COOKIE['elementValues'])) {
        /* 
            Cookie values are stored like JSON
        */
        $raw = json_decode($_COOKIE['elementValues'], true); //cast to array
        var_dump($raw);
        foreach($raw as $input_name => $value) {
            if (isset($checkboxes[$input_name])) {
                $checkboxes[$input_name] = $value; //true/false
            }
        }
    }

    var_dump($checkboxes);


    if (isset($_POST["checkbox1"]) || $checkboxes['checkbox1']) {
        $arguments[] = "AND `2kandunder` = 'yes'";
    }
    if (isset($_POST["checkbox2"]) || $checkboxes['checkbox2']) {
        $arguments[] = "AND `2kto4k` = 'yes'";
    }
    if (isset($_POST["checkbox3"]) || $checkboxes['checkbox3']) {
        $arguments[] = "AND 4kandup = 'yes'";
    }

    $str = '';
    if(!empty($arguments)) {
        $str = implode(' ',$arguments);
    }

    echo 'QUERY FILTER : ' . $str;
?>

    <body>
        <form action="#" method="POST">
            <?php
                foreach($checkboxes as $input_name => $checked) {
                    echo '<input type="checkbox" id="'.$input_name.'" name="'.$input_name.'"'.($checked?' checked':'').' />';
                }
            ?>
            <input type="submit" />
        </form>
